Brushes are sized 2” less than the machine, allowing the brush to clear the apron/shroud of the machine and any bristle flair caused by the normal use of the brush.

Nylon grit brushes are effective, convenient and economically sound replacements for disposable pads, often lasting more than 100 times longer without clogging. As the grit number increases, the brush gets softer. Silicon carbide grit is impregnated into the nylon filament at the point of extrusion, making it part of the bristle. The result is effective cleaning with a longer brush life.
